Supplementing broilers with different levels of fructooligosaccharides (FOS) under stress conditions, such as higher stocking densities and recycled litter that were not a significant difference in broiler performance, carcass quality and meat quality between the FOS-supplemented groups and the control group (p>0.05). FOS supplementation improved intestinal health by increasing the villus height to crypt depth ratio Lactobacillus populations increased, and Escherichia coli decreased with FOS supplementation. The heterophil-to-lymphocyte ratio was reduced which indicated lower stress.

This study explores the design, production, and installation of 3D-printed modular artificial reefs (3DMARs) at Koh Khai, Chumphon Province, Thailand, through a design thinking framework. Collaborating with SCG Co., Ltd. and the Department of Marine and Coastal Resources, the research establishes design criteria and installation methods, utilizing content analysis and qualitative research. Key principles such as modularity, flexibility, environmental sustainability, and usability are identified. The user-centered approach optimizes the 3DMARs for transport and deployment, enabling local community involvement and fostering sustainable practices. The modular design supports scalability, enhancing marine habitats and coral larval settlement. Furthermore, underwater monitoring techniques enable site-specific data collection, allowing for the generation of digital twin models. This research offers a practical framework for marine ecosystem restoration and empowers coastal communities in Thailand and beyond

The aim of experiment was to study the pyrolysis oil derived from sorted landfill plastic waste that had been buried for 15 years by the Nonthaburi Provincial Administrative Organization. The pyrolysis oil was produced using a Fixed-Bed Reactor at 450 °C for 1.5 hours with LPG as the feedstock, with the goal of using the pyrolysis oil as an alternative fuel. The experiment was conducted under four different conditions : (1) plastic waste buried in a landfill that has not been washed but has been reduced in size, (2) plastic waste buried in a landfill that has been washed and has been reduced in size, (3) plastic waste buried in a landfill that not has been washed and has not been reduced in size, (4) plastic waste buried in a landfill that has not been washed and has been reduced size, with activated carbon used as a catalyst. The experiment revealed that three products were produced : Oil, gas, and char in different quantity. The pyrolysis oil were compared in terms of quality based on pH, Heating value, Moisture content, Functional group, and Chemical Composition. The pyrolysis oil we obtained will be referenced according to the criteria from the Department of Energy Business. The analysis results of the pyrolysis can explain which conditions are suitable for replacing fuel oil in industrial It is therefore one of the approaches that helps manage plastic waste in landfills, reducing the quantity by converting it into usable energy.

Mangosteen peel (Garcinia mangostana Linn.) extract using hot water (MPE) has been shown to have antibacterial potential in freshwater sea bass (Lates calcarifer) larvae infected with Aeromonas hydrophila. In vitro studies showed that MPE has a minimum inhibitory concentration (MIC) of 25 ppm and a minimum bactericidal concentration (MBC) of 25 ppm. In vivo, sea bass larvae were immersed in various concentrations of MPE at 0 ppm (control), 20 ppm, 40 ppm and 60 ppm, respectively, for 7 days with A. hydrophila. The results showed that the MPE-treated group had a higher survival rate compared to the control group. Hematological parameters showed that the MPE-treated group had significantly increased red blood cell (RBC), white blood cell (WBC) and hemoglobin (Hb) concentrations compared to the control group. In addition, the water quality parameters were not significantly different, except for ammonia concentration, with MPE having an ammonia concentration of 60 ppm being the lowest. All results can indicate that MPE can improve the antibacterial potential and the culture potential of sea bass larvae.
